论文摘要
非局部性是量子物理学中有趣的话题，通常由某些独特的量子状态介导。在这里，我们研究了一个Weyl Semimetal板，并在将两个潜在的井仅在顶部和底部表面放置时发现了外来的非局部相关效应。这种相关性来自Weyl半法中特殊的Weyl轨道，这是拓扑结构理论中构成对应关系的结果。进一步发现了巨型的非局部传输信号和韦尔费米片的身体分解，可以用作实验验证这种非局部相关效应的特征。我们的结果扩展了非局部性家族的新成员，并具有潜在的应用程序来设计具有精美功能的新电动设备。
Nonlocality is an interesting topic in quantum physics and is usually mediated by some unique quantum states. Here we investigate a Weyl semimetal slab and find an exotic nonlocal correlation effect when placing two potential wells merely on the top and bottom surfaces. This correlation arises from the peculiar Weyl orbit in Weyl semimetals and is a consequence of the bulk-boundary correspondence in topological band theory. A giant nonlocal transport signal and a body breakdown by Weyl fermions are further uncovered, which can serve as signatures for verifying this nonlocal correlation effect experimentally. Our results extend a new member in the nonlocality family and have potential applications for designing new electric devices with fancy functions.
